IMPROVEMENT IN MASHING-MAC HINES.

The Schedule referred to in these Letters Patent and meking paxt of thesame To all whom it may concerm,

like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention,'Iwill proceed to describe it.

'My invention relates to mashing-machines for brewers; and

It consists in a novel""manner .of constructing an automatic machine formixing. the mash, whereby it can be made of a more uniform thicknessthan by any method heretofore practiced, and by which the thickness ofthe mash produced may be regulated at will.

In the drawing Figure 1 is a side elevation of my improved machine;

Figure 2 is a vertical cross-section of the same, taken on the line a:a: of fig. 1; and

Figure 3 is a view of three of the feed-regulating slides.

A is a cylindrical metal vessel, made with double orhollow walls, andhaving its upper end drawn in, and formed with" a neck, 0.

The space between the edges of the inner and outer walls I closetightly, and perforate the inner wall, a, with a great'number of veryfine holes, 1) b, passing obliquely upward from the inside, as shown.

The opening down through the vessel I make smaller at the lower than atthe upper end, as shown in fig. 2.

- B.is a tapering vessel, largest at its lower end, suspended within,and, at the center of the vessel A, by

oval'pipes, f, communicating with the space between p the two walls ofvessel A. v

This vessel B, I also provide with fine perforations,

with an upward inclination similar to those of the wall a. a

D is a conical head or cap, secured to the top of the vessel B, todistribute the descending malt equally around in the annular spacebetween the vessels A and B. l

E arepipes communicating with the space in the hollow walls, and throughwhich the hot water is forocd'into the space i and vessel B.

F is a box or chute, located on top of the vessel A, and provided with adoor, G, and window, H, as

shown.

I is a metal regulating slide, lying across the chute,

and being provided with a circular opening, the size of which regulatesthe feed or flow of the malt.

J is a hopper to contain the malt, located on top of the chute, andprovided. witha slide. K, for closing its mouth. a r

In operating my, device the hot water is forced in through the pipes E,filling ,the space i and vessel B, and discharging through theirperforations, upward and outward, into the annular space L.

Theslide K is then drawn out, and the malt from the hopper allowed todescend through the chute F and slide I, and strike upon cap I), whichthrows it out-T ward into the space L, down through which it falls,becoming thoroughly mixed in its passage with the water, which isthrownamong and against it,'and is then discharged below in the form ofa thoroughly mixed and homogeneous mash.

The pipes E are provided with cocks, (I, by which to regulate or shutoff the flow of water;

Each machine I provide with several of the slides I I, having holes ofdifferent sizes, and with one slide havingno opening, so that, by usingone or another of these slides, the operator may regulate the flow ofthe malt, and thereby the thickness of the mash produced. By making thepipes f'of an oval form, as shown, the accumulation of malt on top ofthem is prevented The glass window H affords the operator a convcnientmeans for observing whether or not the malt is running down properly,and the door G a means for gaining access to the interior for anypurpose.

\Vhen the machine is not in operation, the solid slide I is inserted toprevent the escapeof steam.

By this manner of construction, dividing the water into a great manyvery fine streams, and giving these streams an upward direction, throughand among the descending malt, I obtain a more thorough and satis-'factory mash than can be produced by any other apparatus in use.

Having thus described my invention,

\Vhat I claim is- Y 1. A mashing-machine, having a conical perforatedcylinder, B, arranged within a cylindrical vessel, A, provided with aperforated hollow wall, a, so as to leave a space between them, withdownward incliu- I ing walls, substantially as herein described, for the'purpose of allowing the water to be injected into and against thefalling mash in opposite directions, as set forth.

2. In combination with the cylinder B, constructed and arranged asherein described, the conical cap D, mounted thereon. substantially asand for the purpose set forth.

3. The opening ,H, covered with glass or other transparent material, inthe chute F, for the purpose of permitting the inspection of theinterior during cylinder B, when constructed and arranged for opthedischarge of the malt. eration substantially as herein described, andfor the 4. In combination-with a mashing-machine, conpurpose set forth.structed as herein described, the slides I, having dif- ARTHUR HARRIS.ferent sized openings for regulating the flow of the mash, as set forth.

Witnesses: I 5. The pipes E with their stop-cocks d, and con- D. M.GONNAC, neeting pipes j; in combination with the vessel A and EUG. M.SMYsER.
